Outflow of the intermediate water in the East/Japan Sea through the Tsugaru Strait is inferred from the fact that profiling floats deployed below the sill depth in the central East/Japan Sea moved out to the Northwest ...

Argos recently implemented a new algorithm to calculate locations of satellite-tracked animals that uses a Kalman filter (KF). The KF algorithm is reported to increase the number and accuracy of estimated positions over ...

Patterns of overwash deposition observed within back-barrier sediment archives can indicate past changes in tropical cyclone activity; however, it is necessary to evaluate the significance of observed trends in the context ...

Management of marine ecosystems increasingly demands comprehensive and quantitative assessments of ocean health, but lacks a tool to do so. We applied the recently developed Ocean Health Index to assess ocean health in the ...

Unprecedented summer-season sampling of the Arctic Ocean during the period 2006−2008 makes
possible a quasi-synoptic estimate of liquid freshwater (LFW) inventories in the Arctic Ocean basins.
In comparison to observations ...

Eighteen strains of flagellated protists representing 9 species were isolated and cultured from
four deep-sea hydrothermal vents in the Eastern Pacific Ocean: Juan de Fuca Ridge, Guaymas Basin, and both 21°N and 9°N on ...

A field experiment to compare methods of assessing submarine groundwater discharge (SGD) was held on Shelter Island, NY, in May 2002. We evaluated the use of radon, radium isotopes, and methane to assess SGD rates and ...

United States and Canadian governments have responded to legal requirements to reduce human-induced whale mortality via vessel strikes and entanglement in fishing gear by implementing a suite of regulatory actions. We ...

Climate simulation with numerical oceanic models requires a proper parameterization
scheme in order to represent the effects of unresolved mesoscale eddies. Even though
a munber of schemes have been proposed and some ...

Thorium-234 is increasingly used as a tracer of ocean particle flux, primarily as a means to estimate particulate organic carbon export from the surface ocean. This requires determination of both the 234Th activity ...

The Atlantic and Arctic Oceans are critical components of the global carbon cycle. Here we quantify the net sea–air CO2 flux, for the first time, across different methodologies for consistent time and space scales for the ...

This review provides an assessment of sediment trap accuracy issues by gathering data to address trap hydrodynamics, the problem of zooplankton "swimmers," and the solubilization of material after collection. For each ...

The dynamical aspects involved in the assimilation of altimeter data in a
numerical ocean model have been investigated. The model used for this study
is a quasi-geostrophic model of the Gulf Stream region. The data that ...

The reductive assimilation of sulfate into cellular organic sulfur
compounds was studied in aerobic marine bacteria, with emphasis on the
relationship between sulfur metabolism and protein synthesis. The goal of
the ...

Due to the seriously endangered status of North Pacific right whales Eubalaena japonica, an improved understanding of the environmental factors that influence the species’ distribution and occurrence is needed to better ...

The rise and diversification of shelled invertebrate life in the early Phanerozoic
took place in two major steps. During the Cambrian Explosion at ca. 540 Ma a
large number of new phyla appeared over a short time interval. ...
